PROBLEM TO BE SOLVED: To provide a laminated iron core of a rotator that can fix a magnet in a rotary shaft insertion hole.SOLUTION: A laminated iron core 100 of a rotator includes, as a first iron core member 2b constituting one lamination of the laminated iron core 100, a rotary shaft insertion hole 25b that a rotary shaft 5 penetrates, a plurality of magnet insertion holes 26 that a magnet 1 penetrates, a rotary shaft abutting portion 21b which has an outer peripheral part separated from a main body of the first iron core member 2b, and projects inward from a wall surface of the rotary shaft insertion hole 25b to press the rotary shaft 5 when the rotary shaft 5 is inserted into the laminated iron core 100, and a first magnet abutting portion 23b which presses a radially inner side face of the laminated iron core 100 of the magnet 1 outward in a radial direction of the laminated iron core 100 as the rotary shaft abutting portion 21b presses the rotary shaft 5. |
